Abstract: This application relates to a frictional electricity generator increasing output transfer efficiency. In one aspect, the frictional electricity generator includes a housing and a power generation element which is arranged in the housing and in which a + position pole and a − position pole are arranged according to the movement of a positive charge and a negative charge by friction. The + position pole and the − position pole of the power generation element may be arranged at a distance of a predetermined angle on a plane so as to minimize energy loss due to mutual repulsion, and may be connected to each transmission path.

Abstract: This application relates to a display stream compression (DSC) encoding method in a DSC encoding hardware device. In one aspect, the method may include applying a DSC encoding setting variable set by a core. The method may also include reading an input video, received through a video receiver, from an image buffer in which the input video is stored. The method may further include receiving a DSC encoding operation execution command from the core and executing a DSC encoding operation on the basis of the DSC encoding setting variable.
